Electricity will be the backbone of the entire energy system. We are evolving this system. And we are evolving too. From October 2021 we will become Hitachi Energy!

The EconiQ high-voltage portfolio of products, services and solutions contribute towards a carbon neutral-future and accelerate the green energy transition.

With green energy transition across the globe to demanding energy consumers, High-Voltage Direct Current (HVDC) continues to shape the grid of the future where electricity will be the backbone of our energy system.

Sustainability 2030 is Hitachi Energy’ new strategic plan for sustainability, where we summarize the main commitments to act and drive business in a sustainable way. 

Electricity. Like the air we breathe, it's invisible, but it is essential to life. Together, with customers and partners, we are committed to accelerating the energy transition towards a carbon-neutral future.
